Mega 16 is an 8-bit microcontroller with advanced RISC simplified instructions and built-in A/D, which can support low-voltage online Flash and EEPROM writing functions. At the same time, it also supports programming in advanced languages such as Basic and C. Using it to design electronic clocks is not only low in cost, simple in hardware, but also easy to realize system transplantation. This paper introduces how to design an electronic clock by using AVR series single chip microcomputer Mega 16 and 1602 character liquid crystal, and gives the corresponding circuit principle and some language programs.
Seeking adoption is a satisfactory answer.
